Abstract Lodgepole pine (Pinus contorta) trees of two different seed origins, one a poor quality host (Alaskan lodgepole pine), the other a good quality host (south coastal lodgepole pine), were infested with known numbers of eggs of the pine beauty moth, Panolis flammea. Each tree had paired... mehr

This paper analyses the factors influencing the design of urban open space from the users' perspective. A questionnaire survey has been carried out in Hong Kong to identify the importance of each design attribute with the aid of the analytic hierarchy process. The results show that microclimate... mehr

Approximately 3·9 kb of DNA, centromere proximal to the previously sequenced Y′ element at the right end of chromosome XV in Saccharomyces cerevisiae strain YP1, has been sequenced. A number of the known sub-telomeric repeat sequences were identified, including Y′, core X and STRs A, B. C... mehr

We report the complete sequence of a 9·2 kb fragment next to and including the right telomere of Saccharomyces cerevisiae chromosome XIV. Four open reading frames (ORFs) longer than 100 amino acids were observed in the sequenced segment. One ORF (378 codons) does not show any significant... mehr

Abstract Momentary brain electric field configurations are manifestations of momentary global functional states of the brain. Field configurations tend to persist over some time in the sub-second range (“microstates”) and concentrate within few classes of configurations. Accordingly, brain... mehr

The temporal structure and high brilliance of the X-ray beams producedby third-generation synchrotrons open up new possibilities in time-dependentdiffraction and spectroscopy, where timescales down to the sub-nanosecondregime can now be accessed. These beam properties are such that one can... mehr

Abstract The nucleotide sequence of a 5,520-bp EcoRI restriction fragment of avian infectious laryngotracheitis (ILTV) DNA was reported and submitted to GeneBank with an accession number of AF001078. Computer prediction revealed one large potential open reading frame (ORF) with sequence similar... mehr

English has several classes of transitive verbs which can optionally appear without an undergoer. Despite their similar syntactic sub-categorization, there are at least three different semantic subclasses that allow undergoer omission. Information sources based on surface structure, for example,... mehr

Abstract This paper proposes a hybrid Space-Time Division Multiple Access (S-TDMA) for broadband indoor wireless systems using sectored antennas. It is shown that portables which are located in different sectors of the indoor microcell may be able to reuse the same frequency and the same time... mehr

Summary 1. A series of 4 experiments examined the performance of rats with retrohippocampal lesions on a spatial water-maze task. 2. The animals were trained to find and escape onto a hidden platform after swimming in a large pool of opaque water. The platform was invisible and could not be... mehr
